Blood Test Could Unlock Better Treatment And Diagnosis For Depression

Screening for a blood molecule may lead to improved depression treatment.

Some patients with depression have decreased levels of the blood molecule acetyl-L-carnitine, according to a study published in Proceedings of the National Academy of Sciences. Screening blood for acetyl-L-carnitine could help improve the process of diagnosing major depressive disorder. The discovery could also lead to better treatment options for patients with major depressive disorder.

Depression is a common mood disorder, and it is the leading cause of disability worldwide, according to the World Health Organization.

“It’s the number one reason for absenteeism at work,” says Natalie Rasgon, a doctor and professor of psychiatry and behavioral sciences at Stanford University, in an interview with the Stanford Medicine News Center.

Acetyl-L-carnitine is a blood molecule that the body produces naturally. It is involved in regulating energy and it influences the gene that controls glutamate, which is a chemical that is involved in brain function.
